    Abstract: This spherical silica powder is configured such that when the spherical silica powder is measured using a wet flow type image analyzer, a sphericity of a particle size of more than or equal to 5 μm and less than 10 μm is represented by S1, a sphericity of a particle size of more than or equal to 10 μm and less than 20 μm is represented by S2, a sphericity of a particle size of more than or equal to 20 μm and less than 30 μm is represented by S3, a sphericity of a particle size of more than or equal to 30 μm and less than 45 μm is represented by S4, and a sphericity of a particle size of more than or equal to 45 μm is represented by S5, at least two of S1, S2, S3, S4, and S5 are more than or equal to 0.74.
